“Never before has a single volume contributed such an immense wealth of new information on North American butterflies...James and Nunnallee have literally given Lepidopterology in North America a brand-new start.”

—Dr. Andrew D. Warren, McGuire Center for Lepidoptera and Biodiversity, University of Florida


“The publication of James and Nunnallee, or ‘the Daves’ as we know them, is a matter for unreserved celebration, not only for lepidopterists and nature lovers of all stripes, but for anyone who cares about our butterflies’ lives, futures, conservation management, and the plants with which they have co-evolved.”

—Robert Michael Pyle, author of Mariposa Road: The First Butterfly Big Year
